What is PostgreSQL:

PostgreSQL is a free, open-source relational database management system that focuses on SQL conformance and extensibility. With over 30 years of active development, PostgreSQL is one of the most widely used open-source database tools in the world. PostgreSQL is very stable, it supports different functions of SQL, like foreign keys, subqueries, triggers, as well as different user defined types and functions. This database management system offers features usually found only on commercial systems like Oracle and SQL Server. It can process the most complex types of data, and offers optimal performance in all circumstances. The system also and above all owes its popularity to its open source nature.
